This invention provides an interleukin-31 (IL-31) production inhibitor and a pharmaceutical composition comprising the inhibitor. The invention also provides a novel compound useful as an active ingredient for an IL-31 production inhibitor. These comprise a compound represented by the following formula (1) or a salt thereof as an active ingredient:
wherein
A is a -NH-N=C(R1)- group, a divalent N-containing 5-membered heterocyclic group, or a -NH-CO- group, wherein R1 is a hydrogen atom or a C1-4 alkyl group,
B is the same or different and is a C1-6 alkyl group optionally having one hydroxyl group, a mono or di(C1-6 alkyl)amino group optionally having one hydroxyl group, a halogen atom, a halo C1-6 alkyl group, a C2-6 alkynylene group, or a carboxy group, wherein at least one C1-6 alkyl group in the mono or di (C1-6 alkyl) amino group is optionally attached to a carbon atom adjacent to a carbon atom in the phenyl group to which it is attached, to form a 5- to 6-membered ring, and
n is an integer of 1 to 5.
本发明提供了一种白细胞介素-31(IL-31)生产抑制剂,以及包含该抑制剂的药物组合物。本发明还提供了一种新型化合物,可用作IL-31生产抑制剂的活性成分。这些化合物包括以下式(1)所示的化合物或其盐作为活性成分:
其中,
A是-NH-N=C(R1)-基团、含氮的5元杂环二价基团或-NH-CO-基团,其中R1是氢原子或C1-4烷基;
